Subject: [PATCH v2] SUNRPC: Add source address/port to rpc_socket* traces
Date: Mon, 13 Dec 2021 08:38:48 +0000 [thread overview]
Message-ID: <20211213083848.43930-1-plambri@redhat.com> (raw)
The rpc_socket* traces now show also the source address
and port. An example is:
kworker/u17:1-951 [005] 134218.925343: rpc_socket_close:
socket:[46913] srcaddr=192.168.100.187:793 dstaddr=192.168.100.129:2049
state=4 (DISCONNECTING) sk_state=7 (CLOSE)
kworker/u17:0-242 [006] 134360.841370: rpc_socket_connect:
error=-115 socket:[56322] srcaddr=192.168.100.187:769
dstaddr=192.168.100.129:2049 state=2 (CONNECTING) sk_state=2 (SYN_SENT)
<idle>-0 [006] 134360.841859: rpc_socket_state_change: socket:[56322]
srcaddr=192.168.100.187:769 dstaddr=192.168.100.129:2049 state=2 (CONNECTING)
sk_state=1 (ESTABLISHED)
